Space Entrepreneurship in High Schools: What’s Possible Now

By Seda Hewitt, Interstellar Communication Holdings Inc., United States

There’s something quietly revolutionary happening in high schools around the world.

Not just in science labs or coding clubs—but in the space above us. What used to be the stuff of science fiction or advanced university research is, in some places, now part of after-school programs. We’re talking about satellites. Real ones. And even more interesting? They’re being built, tested, and in some cases, launched by teenagers.

It still catches people off guard.

“Wait, high schoolers are putting things into space?” Yes. And the tools to do it—hardware, software, global collaboration—are finally accessible enough that it’s not just theoretical anymore.

At Interstellar Communication Holdings Inc., based in the United States, we’ve worked with schools and educators across continents through our icMercury platform and our HADES‑ICM PocketQube missions. And while these satellites are small—sometimes just 5 centimeters across—the ideas behind them are anything but.

Let’s talk about what’s changed. Why now. And what’s next.

Access Isn’t the Problem Anymore

Ten years ago, launching a satellite as a high school student was basically impossible unless you were part of a highly funded academic institution or a national program. Everything—from development costs to launch coordination—required massive capital and insider knowledge.

Today? That’s shifting.

Open-source tools mean students can write and test flight code from home.

Software-defined radios (SDRs) allow ground stations to be built for under $100.

Rideshare missions through groups like SpaceX, Exolaunch, and Alba Orbital have made launching a satellite dramatically cheaper.

And perhaps most crucially: there’s a growing ecosystem of mentors, organizations, and platforms (like icMercury) ready to support first-time space builders.

The result? Launching a satellite isn’t just possible. It’s becoming a capstone project.

A Real Example: Turning a Club into a Mission

One school in South Korea approached us in early 2024. A student-led team had been building a ground station using SDR and open-source satellite tracking software. Their goal wasn’t to launch a full satellite—not yet—but to receive signals from HADES‑ICM, decode them, and contribute data to the public mission dashboard.

It may sound simple, but think about the experience those students are gaining:

Orbital mechanics

Radio frequency theory

Data analysis and telemetry decoding

Collaboration across time zones

Project planning under real-world constraints

This isn’t just textbook STEM. It’s engineering, teamwork, and exploration rolled into something very real.

Entrepreneurship Doesn’t Always Mean a Business

When we say “entrepreneurship,” people often picture startups. Venture capital. Shark Tank-style pitches.

But in high school settings, entrepreneurship sometimes means something quieter. It means:

Starting a program no one else has tried.

Building a small team of peers to tackle a complex challenge.

Figuring out how to fundraise, pitch to school boards, or get parental support.

Learning from failure, because space has a lot of that.

We've seen students design satellite experiments for agriculture, radiation studies, and even low-bandwidth communication relays. Some are meant to help remote communities; others are pure curiosity.

But the spirit is the same: can we do something new, even if we’re not experts yet?

The Role of icMercury and HADES‑ICM

At Interstellar Communication Holdings Inc., we never set out to create a "student platform" per se. But that's exactly what icMercury has become for many schools. A stepping stone. A test bed. A friendly signal in the sky they can point an antenna at and say, “That’s ours. We helped make that happen.”

It’s not always about launching your own payload—although, yes, that’s possible too. Sometimes it’s about joining a mission already in orbit and learning by participating. Listening. Logging data. Asking questions. Getting better.

And that’s where the spark of entrepreneurship starts to take root.

Recognition on the Global Stage

This kind of quiet innovation doesn’t always get headlines, but it should. That’s part of why we’re so honored that Interstellar Communication Holdings Inc. is a nominee for the 2025 Go Global Awards, hosted this November in London by the International Trade Council.

This event isn’t just about who builds the flashiest tech. It’s a gathering of the world’s sharpest minds in business, education, infrastructure, and global collaboration—coming together to share, to learn, to build new bridges.

We’re proud to bring stories like these with us. Stories of students in community labs pointing antennas toward the stars. Of teachers learning alongside their students. Of ambition, scaled small enough to launch—but big enough to change lives.

Final Thought: You Don’t Need to Wait

You don’t need a space agency. You don’t need to live in a city with a launchpad. You don’t need to be a genius.

All you need is a spark. A laptop. A question you can’t quite shake. A group of people who believe they can learn anything, if given the chance.

And maybe a satellite the size of a Rubik’s Cube, orbiting quietly above, waiting to be heard.

Ground Stations 101: How Your Satellite Talks Back

By Seda Hewitt, Interstellar Communication Holdings Inc., United States

Satellites are often seen as the stars of the show—literally orbiting above us, performing science, sending signals, taking images. But the real magic? It happens down here. On the ground. Quietly. Repeatedly. Through a network of unsung heroes called ground stations.

If the satellite is the voice, then the ground station is the ear. And the microphone. And, in a way, the interpreter too. Without it, your satellite might be orbiting beautifully and doing its job, but... no one would ever hear from it. Or be able to talk to it. And that's a lonely kind of success.

At Interstellar Communication Holdings Inc., based in the United States, we’ve spent years working with users building and managing ground stations for our PocketQube missions like HADES‑ICM under the icMercury platform. Whether it’s a classroom using a USB dongle and a homemade antenna or a sophisticated amateur radio setup receiving live telemetry, what we’ve learned is this: you don’t need to be NASA to talk to space.

But how, exactly, does it work?

The Basic Concept: Listen and Respond

A ground station does two main things:

Receives data from a satellite (downlink)

Sends data to a satellite (uplink)

Simple in concept, yes. But each of those actions requires careful timing, precision, and a bit of practice. Why? Because satellites are constantly moving. Fast. A typical low Earth orbit (LEO) satellite like HADES‑ICM travels at about 7.8 kilometers per second. That means it only appears over your horizon for a few minutes per pass.

So your equipment has to be ready. Tuned. Aligned. And sometimes, lucky.

What You Need to Get Started

Here’s what a basic ground station setup might include:

Antenna: Yagi or turnstile antennas are popular for satellite work. They determine how well you can hear the satellite (and whether it can hear you). Directional antennas often work best, but they need tracking.

Software-Defined Radio (SDR): This has revolutionized access to satellite communication. Small USB devices like the RTL-SDR allow even hobbyists to receive satellite data for under $50.

Tracking Software: Because satellites move, you need software that knows where they are at any given moment. Tools like Gpredict or SatNOGS help you predict passes and automate tracking.

Decoding Tools: Once you hear the signal, you’ll need to turn that squiggly audio into readable data. For PocketQubes, this might mean decoding telemetry packets, APRS messages, or even image data in some cases.

That’s the gear. But equally important is patience. And a sense of wonder.

What Talking to a Satellite Feels Like

There’s something humbling about waiting for your satellite to appear on the horizon. You’ve tracked its path. Tuned your radio. Watched the Doppler shift creep across the signal. And then—it’s there. A tone. A ping. A chirp. Something unmistakably artificial, beamed down from something you helped send up.

One of our icMercury users in Brazil built his own UHF ground station from scavenged parts. When he first picked up HADES‑ICM, he didn’t have the software to decode it yet—but it didn’t matter. He knew it was real. And that it was listening.

Beyond the Backyard: Global Ground Networks

Now, here’s where it gets even more interesting. A growing number of organizations and citizen groups are building shared ground station networks, where anyone can access satellite data from receivers around the world.

This is huge for satellites that pass over places where individual users might not exist—or can’t afford equipment. It’s also great for redundancy. If you miss a pass, someone else might catch it.

Networks like SatNOGS have played a big role in this. But there are new platforms emerging every year, many of which integrate with educational programs and open-source missions. We’ve had HADES‑ICM signals relayed from Iceland, Ghana, Thailand, and rural Australia—often by complete strangers just excited to help.

This kind of collaboration, I think, reflects the real spirit of space exploration today. It’s not just centralized anymore. It’s distributed. Democratic. Tangibly human.

Challenges and Real-World Lessons

It’s not always smooth, though.

Sometimes the signal’s weak.

Weather can mess with reception.

Doppler effects require constant frequency shifting.

And occasionally… nothing works, and you don’t know why.

And that’s okay. Every ground station operator learns this. Troubleshooting becomes second nature. Eventually, you start to understand what space noise sounds like. You stop panicking when the waterfall drops. You learn when to wait.

At Interstellar Communication Holdings Inc., we hear these stories every week. Of trial, of error, of breakthroughs at 2 AM. It’s a reminder that communication is a practice, not a guarantee.

Looking Ahead

This November, we’re excited to represent this community of ground station operators—novice and expert alike—at the 2025 Go Global Awards in London, where our company has been nominated.

Hosted by the International Trade Council, this isn’t just another conference. It’s a summit of the world’s most forward-thinking organizations. A place where ideas collide, industries converge, and real-world solutions emerge.

For us, it’s a chance to showcase how something as humble as a ground station can play a role in something as ambitious as democratizing space access.

Final Thought: The Ground Is Where the Sky Begins

A satellite without a ground station is like a message in a bottle without a beach. It floats, it waits, and eventually—it’s forgotten.

But with the right tools, and the right people, that message gets received. Decoded. Shared. Turned into insight. Turned into purpose.

Whether you're a student building your first antenna out of coat hangers, or a seasoned ham operator tracking signals from dozens of missions, know this: you’re part of a conversation. One that crosses borders, orbits Earth, and brings us all a little closer to the sky.
